You should create a function that will perform linear interpolation from a set of measured data. the function should take as input a list of values at which samples were taken, and then another list giving the measurements (you can assume each measurement is a single value) at those values. it should also take in a query value, and should give the best estimate it can of the value at that query. be sure to handle values that are outside of the range, by extrapolating. you should write a program that allows you to test your function by reading the lists from a file where each line of the file is a pair of numbers separated by spaces: the value where the sample was taken, and the measurement at that value. your program should ask the user for the name of the file and for a query value. important: the two lists will correspond to each other: i. e. for the i-th value in the first list, the measurement will be the i-th element of the second list (these are called parallel lists or arrays). but, you should not assume that the input values are in increasing/decreasing order. that is, the values in the first list can be in any random ordering, not necessarily from smallest to largest or largest to smallest. you will have to account for this in your program, and there is more than one way to do so. you should discuss what options you can think of to handle the data arriving in any order like that, and decide what you think the best option for handling it is. extend your program from part (a) so that it will handle not just single values but vector data. your program should ask a user for a file name, and the number of dimensions, n, of the vector data. it should then read from the file, assuming the values at which measurements are taken are the first entry per line, and then there will be n entries, all space-separated. you may find it easier to store your vector data in numpy arrays. your interpolation function should return the vector data either using tuples or using arrays from the numpy module.

Am me for the answer

Mri is one what are your options anyway ?

Infrared sensor is most used sensor in wireless technology where remote controlling functions and detection of surrounding objects/ obstacles are involved. this post will discuss about what is infrared sensor, its working principle, how it works, types, applications, advantages and disadvantages. what is infrared sensor

ir sensor is a simple electronic device which emits and detects ir radiation in order to find out certain objects/obstacles in its range. some of its features are heat and motion sensing.

ir sensors use infrared radiation of wavelength between 0.75 to 1000µm which falls between visible and microwave regions of electromagnetic spectrum. ir region is not visible to human eyes. infrared spectrum is categorized into three regions based on its wavelength i.e. near infrared, mid infrared, far infrared.

wavelength regions of infrared spectrum

near ir – 0.75µm to 3 µm
mid ir – 3 µm to 6 µm
far ir – > 6 µm

working principle of infrared sensor

infrared sensors works on three fundamental physics laws:

planck’s radiation law: any object whose temperature is not equal to absolute zero (0 kelvin) emits radiation.
stephan boltzmann law: the total energy emitted at all wavelengths by a black body is related to the absolute temperature.
wein’s displacement law: objects of different temperature emit spectra that peak at different wavelengths that is inversely proportional to temperature.
key elements of infrared detection system

the key elements of infrared detection system are:

ir transmitter

ir transmitter acts as source for ir radiation. according to plank’s radiation law, every object is a source of ir radiation at temp t above 0 kelvin. in most cases black body radiators, tungsten lamps, silicon carbide, infrared lasers, leds of infrared wavelength are used as sources.

transmission medium

as the name suggests, transmission medium provides passage for the radiation to reach from ir transmitter to ir receiver. vacuum, atmosphere and optical fibers are used as medium.

ir receiver

generally ir receivers are photo diode and photo transistors. they are capable of detecting infrared radiation. hence ir receiver is also called as ir detector. variety of receivers are available based on wavelength, voltage and package.

ir transmitter and receivers are selected with matching parameters. some of deciding specifications of receivers are photosensitivity or responsivity, noise equivalent power and detectivity.
